Naruto is assigned to watch Akamaru, Kiba Inuzuka’s nin-dog, who has recently been acting strangely after being infected by a poison during a mission. This is confirmed when Akamaru begins to violently attack Konoha’s inhabitants, and the ANBU take him into custody, being prepared to kill him if they are unable to cure him. However, this is too much for Kiba, and he rescues Akamaru, attempting to cure him on his own. Naruto pursues Kiba, who refuses to believe that Naruto is attempting to help him. Finally, Kiba’s sister arrives, and with Naruto, attempts to restrain a now giant-sized Akamaru to use an anti-toxin to remove the poison. Kiba succeeds in doing so, although he is nearly killed in the process. It is later revealed that Akamaru tried his hardest to miss Kiba’s vital points, something that Kiba thanks Akamaru for.
